Tapered Drill Bits For Metals
-
Product Highlights- 118° split point tip: the 118° split-point tip design of the step drill bit increases the cutting speed while preventing off-center line when drilling. flat shank design for increased safety and stability, the step drill bit can be better fixed to the pistol to prevent falling off and slipping during the rotation
- Five piece set with 50 sizes: the ladder drill set includes five standard drill bits, which equip with safety clips for easy storage without worrying about falling off and can be used to drill holes of different sizes in different steps.
- Hss titanium coating: the step drill bit set is made of industrial high speed steel and coated by titanium nitride, which can reduce friction and runs cool. step drill bit has excellent durability , high-speed punch, corrosion resistance, and rust resistance.
- Two-fluted design design: step drill bit grooves provide a smoother cut that removes burr chips, dust and chips for faster chip evacuation, while helping to prevent chips from flying, allowing for smoother drilling without heating.
- Widely used: high speed steel step drill bits for metal can be widely used on plastics, wooden boards, cardboard, pvc materials, thin iron plates, aluminum plates (not recommended for stainless steel materials).

Product Highlights
- Application: especially for steel, metal, alloy aluminum, brass, plastic, iron, nickel, copper, cast iron and other structural materials
- Note: the 5/8" bridge reamer bit is not a drill bit, only aligns the reamer with the pre-drilled hole. if you need to enlarge the hole to 5/8". must have a 3/8" pre-drilled first, then reamed to 5/8"
- Drill bridge reamer:heavy-duty high-speed steel bridge reamers,expand or align existing holes through mild steel, alloys, aluminum, wood, plastic, fiberglass, or any material of similar hardness prior to rivet or bolt installation, deburring and trimming of holes in structural materials
- Design: tapered point design allows reamer bits to enter irregular overlapping holes, aligning bolt holes
- Material: made of high-quality steel, high toughness, high temperature resistance, corrosion resistance, long service life

Product Highlights
- Jam-free performance ----- the dual-flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
- Larger size ----- our drill bit is bigger in size so it can drill holes with larger dimensions.
- Durable titanium coated bits ----- the step drill bit is made from upgraded high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. the titanium coating makes the drill bit more durable so that it can last for years with uncompromised quality.
- Universal compatibility ----- the rapid strike tip drills twice as fast as the average step drills and can drill acrylic, pvc, wood, aluminum and iron sheets up to 0.2’’ in thickness.
- One bit for all ----- the bit comes with 12 hole sizes: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm. , saving you time and efforts to change bits, quadrupling your drilling efficiency compared to competition.
